Redvein dock
Also known as: Blood dock
People grow redvein dock (Rumex sanguineus) primarily as ornamental foliage. It’s indigenous to Eurasia and northern Africa. Although it’s edible, it should only be eaten in small amounts because it contains oxalic acid, which can cause stomach distress. Its tender young leaves can be eaten raw or cooked, but older leaves are bitter and tough. It tastes like chard or spinach.

Soil Type
Water: Redvein dock thrives in consistently moist soil and prefers regular hydration, with weekly watering recommended. While it can tolerate short dry spells, it significantly benefits from rainwater, which offers ideal pH balance and nutrients crucial for its growth as an herbaceous perennial.
Fertilize: Fertilize redvein dock monthly with high nitrogen fertilizers during the growing season at half-strength, avoiding direct leaf contact. In fall and winter, reduce to every 6-8 weeks. Water thoroughly post-fertilization, and use organic options to enhance soil health while monitoring for over-fertilization stress.
Pruning: Redvein dock has striking veined leaves that enhance garden aesthetics. To promote vigor and prevent legginess, prune in early to late spring. Regularly trim damaged leaves and spent flower stalks for more blooms. These practices maintain a healthy, attractive redvein dock.
Propagation: Redvein dock is best propagated by sowing in Spring, exhibiting average propagation difficulty. Success is indicated by initial sprouting, and maintaining optimal moisture levels enhances propagation outcomes.
Repotting: Repot redvein dock every 2-3 years in early spring, choosing a pot 2 inches larger to support growth. Post-repotting, maintain consistent moisture and avoid direct sunlight for optimal recovery and robust foliage development.
